The base of the triangle is x² + 2x + 4 The height of the triangle is 2x² + 2x + 6 The area of the triangle is A = (1/2) b h Substituting A = (1/2)(x² + 2x + 4)(2x² + 2x + 6) Which can be expanded or factored
A.) it opens up because it is positive. B. The vertex is a minimum, because it opens up C/ The axis of symmetry is X=-1, the Vertex is (-1,-2). The Y interecept is y= -1
